ll ure l' shows the Whole of a tank in Jerse sec ion.

2 5 relate to the Wells constructed according to e modifications'.

ln cese of l, there is applied to the Whole ci the surface olif themetal (ll primary sheet of fabric b impregnated Wit-hsolution ofyulcnnizeble rubber;

(2) Upon the primary sheet e layer c of naturel crude rubber orunvulcenized caoutchouc g (3) Upon the leyer of caoutchouc c e secondsheet oi Afabric l similar to the pri. niery sheet L.

The two sheets or fabric t and al have for their object to hold thecfoutchonc c in such e wey to forni e or covering for the 'tenlr a.

This iinin sary ope of has naturally in it the necesn :tor passage o'objects or parte which 'project yond the tzinl; a, such es the filling"plug9 level indicator, etc.

After it has been applied the covering constructed as has been describedis subjected to the operation of yulcunizetion, the

` bullets or by smell object or which is to render the two sheets ofrubric t and u'. rigid and to canse the iii-st one to adhere closely tothe Well or the reser- 1Voir o. The layer c contained between the twosheets ot Afabric does not undergo any change end remains ettsclrable bythe petrol.

ln cese of perforation: the petrol coroniences to dem the flrst oozingsdissolve the nonyulcanized caoutchouc c 1which softens, spreads outbetween the two sheets or" fabric and automatically stops up theperoret-ion. lt Should he noted that the vtwo sheets oi fabric and lplay a part in the stopping up of the openings. Ets a metter of feetwhen a bullet passes through, the threads or' these sheets of labric `rebroken but they are not carried sway by the bullet they thus tonnescreen which serves for the support of the plastic substance othecaoutchouc c and facilitate the egglomeration thereof. ,Y

The two incdied constructional forms of the composite covering of rubbercloth and rubber which is not vulcanized, described `arbore, concern`principally the replacement of the sheet ot fabric by caoutchouc, eswell as the arrangements which permit ot 'the softening of the differentlayers of the protectinzgr envelop.

ln the first, shown in Fig. 2, the rubber coated fabrics previouslyplaced on either side or the sheet or unvulcanzed rubber are replaced bysheets of vulcanized rubber.

rlhe metal Well of the reservoir is shown at A, e rst vulcanized sheet Boit from 2 to 3 millimeters in the thickness is applied to this well,thenupon this sheet is placed the non-vulcanized sheet C, which may befrom .7 to l0 millimeters thick. Finally the whole is covered over bythe vulcanized sheet D from 2 to 3 millimeters thick.

lt will be seen that the Wall thus constructed is always based .upon thesaine principle es that above described but by the substitution orn theSheets of rubber C and D which surround the non-vulcanized Sheet greaterelasticity und suppleness are obtained, which gives to the Whole when itis necessary a more ei'icacious protection.

The different layers o" caoutchouc may be stuck together cold, but thevulcenization rives to the whole protecting mass .more homogeneity. lnthe course of this opere; tion, the sheet c which does not contain anysultnn' or very little oi it, does not undergo L.' w .L
